Revisión del género Noticastrum (Compositae-Astereae)

Elsa Matilde Zardini


The genus Noticastrum De Candolle (Compositae-Astereae) is a South American segregate of Aster differing from the latter mainly in achene morphology.
Nineteen species of perennial herbs and small shrubs are here recognized, along with a hybrid which has been morphologycally and palynologycally studied. Except for the Chilean species, all of them have been studied in the field. The species are described and illustrated. A number of synonyms are proposed, based on the study of the nomenclatural types which have been analyzed for all taxa except the one remaining as a "doubtful taxon".
Two keys have been prepared: one to separate Noticastrum from its New World generic relatives. The other to identify the species of Noticastrum, based primarily on
ligule length —a character defining two groups of species—, ligule color, hair type, involucre shape and habit.
